Power electronics systems on large ships act as multimegawatt microgrids, powering propulsion and all other onboard electrical equipment. These systems often require multimillion-dollar investments and a year or more to build. As a result, engineering teams that develop the control software often lack access to feature-complete hardware until late in development.
Leonardo DRS engineers use MATLAB® Simulink®, Simscape Electrical™, Simulink Real-Time™, and HDL Coder™ to model shipboard power electronics systems and perform real-time hardware-in-the-loop (HIL) tests on an FPGA module in Speedgoat real-time target hardware.
“Using the HIL workflow we implemented with MATLAB and Simulink, we ensure that our equipment will perform the way we expect in the customer environment for a fraction of the cost of setting up physically equivalent hardware and additional testing infrastructure,” says Chris Harper, electrical systems engineer at Leonardo DRS. “We can test day or night, with or without hardware, while reducing the chances of damage to a full-scale system.”
